Pagination

[danbraunai]

Converts TextNeuronActivations vis to handle multiple text samples and their corresponding activations. Before: After:

Issues:

• When trying to render the updated component in python (in development_mode), bootstrap (which is required for the pagination) fails to load properly, causing a broken pagination.

Possible additions:

• Make backward compatible/allow a user to enter a single list of tokens and activations as opposed to nested lists.

Closing this as I'll be making a new PR with a setup that doesn't include react-paginate (which seems to want bootstrap for styling).
